427842 ÷ 30 
The aim is to understand the frequency of 30 in 427842.

Step 1:
30 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 30

Step 2:
If we divide 42 by 30, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 30 from 42, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 30

Moving on to step 3:
30 goes into 127 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 120 from 127 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 30

Advancing to step 4:
The number 30 fits into 78 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Subtract 60 from 78 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 30

Advancing to step 5:
When dividing 184 by 30, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
Deduct 180 from 184 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 30

Advancing to step 6:
When dividing 42 by 30, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 14261.0
If we subtract 30 from 42, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
30 goes into 120 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14261.4
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14261.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14261.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 14261.4 with a remainder of 0.0.
